Security update for the Linux Kernel (Live Patch 34 for SLE 12)
This update for the Linux Kernel 3.12.61-52_128 fixes several issues.
The following security issues were fixed:
- CVE-2019-9213: Expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bsc#1128378).
- CVE-2019-7221: Fixed a user-after-free vulnerability in the KVM hypervisor related to the emulation of a preemption timer, allowing an guest user/process to crash the host kernel. (bsc#1124734).
- CVE-2018-5391: The Linux kernel was vulnerable to a denial of service a
Security update for the Linux Kernel (Live Patch 35 for SLE 12)
This update for the Linux Kernel 3.12.61-52_133 fixes one issue.
The following security issue was fixed:
- CVE-2018-16884: A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time could make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user could cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bsc#1119947).

This update for the Linux Kernel 3.12.61-52_133 fixes several issues.
The following security issues were fixed:
- CVE-2018-9568: Prevent possible memory corruption due to type confusion in sk_clone_lock. This could lead to local privilege escalation (bsc#1118319).
- CVE-2018-5848: Fixed an unsigned integer overflow in wmi_set_ie. This could lead to a buffer overflow (bsc#1097356).
Security update for the Linux Kernel (Live Patch 31 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_104 fixes one issue.
The following security issue was fixed:
- CVE-2018-18386: The drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bsc#1112039).
Security update for the Linux Kernel (Live Patch 29 for SLE 12)
This update for the Linux Kernel 3.12.61-52_106 fixes several issues.
The following security issues were fixed:
- CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c mishandled sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations (bsc#1110233).
- CVE-2018-14634: An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable (bsc#1108963).
- CVE-2018-146
Security update for the Linux Kernel (Live Patch 29 for SLE 12)
This update for the Linux Kernel 3.12.61-52_106 fixes several issues.
The following security issues were fixed:
- CVE-2018-5390: Prevent very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming TCP packet which can lead to a denial of service (bsc#1102682).
- CVE-2018-10902: It was found that the raw midi kernel driver did not protect against concurrent access which lead to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(), allowing a malicious local attacker to use this for privilege escalation (bsc#1105323).
Security update for the Linux Kernel (Live Patch 34 for SLE 12)
This update for the Linux Kernel 3.12.61-52_128 fixes several issues.
The following security issues were fixed:
- CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system (bsc#1099306).
- CVE-2018-10853: A flaw was found in kvm. In which certain instructions such as sgdt/sidt call segmented_write_std didn't propagate access correctly. As such, during userspace induced exception, the guest can incorre

The following security issue was fixed:
- CVE-2018-3665: System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially have allowed a local process to infer data from another process via a speculative execution side channel (bsc#1090338, bsc#1096740).
